Behind the north stoa of the central court is the "hypostyle hall" and its antechamber. Above these rooms, on the upper storey, there was a hall of equal size, interpreted as a ceremonial banquet hall. To the west of these rooms, a stone paved corridor connects the central court with the north court, which is surrounded by workshops and storerooms, and with the NW court, also called "court of the dungeon". To the west of this lie the official rooms of the palace: at the centre, the reception hall with the typical Minoan polythyra, and behind this, the sunken lustral basin.
